Title: Method for reducing interference by decreasing laser coherence in a confocal scanning microscope.
Inventor: STORZ RAFAEL
IPC: G02B21/06
Filed: 2001-08-24
Abstract: A method for illuminating an object with light 2 from a laser light source 3, preferably in a confocal scanning microscope 1. With the method according to the invention, it is possible to reduce the coherence length of the laser light, so that disruptive interference phenomena can be substantially eliminated. Should interference phenomena be formed, these are to be influenced in such a way that they have no effect on the detection. The method is characterized in that the phase angle of the light field is varied by a modulation means 4 in such a way that interference phenomena do not occur in the optical beam path, or occur only to an undetectable extent, within a predeterminable time interval. Modulation means 4 may comprise an electro optical modulation (EOM), mirror, lens or beam splitter. Alternatively, the modulation means 4 may modulate the laser directly by switching it on and off, changing laser intensity and so on.

Title: Fault detection in an AC power line
Inventor: SCOTT GORDON BRYON
IPC: H02H3/38
Filed: 2002-11-13
Abstract: An apparatus and method for producing a trip signal to activate a circuit breaker in an alternating current power line, eg. a three phase AC supply. The apparatus comprises a sensing circuit, a comparison circuit, a fault discriminator and a trip signal generator. The sensing circuit measures 206 the current in the power line and the phase difference between the current and the voltage. The comparison circuit then compares 208 the measured values of phase difference and current with values characterising a fault condition, and generates a fault indication signal when a fault condition arises. The fault discriminator responds to the fault indication signal and discriminates 212 between a first class of fault 214 wherein the mean current after fault indication increases relative to its value before fault indication, eg. short circuit, and a second class of fault 220 wherein the mean current after fault indication does not increase relative to its value before fault indication, eg. arcing. In the case of the second class of fault where the mean current has decreased, the fault discriminator determines whether the current returns to its normal level within one AC cycle, and thereby further discriminates between arcing due to a defective connection 220 and arcing due to normal switch gear operation 224. In the case of a genuine fault of either class, a trip signal is generated 216,222 by the trip signal generator.

Title: System and method for searching,finding and contacting dates on the internet in instant messaging networks and/or in other metods
Inventor: MAYER YARON
IPC: G06F17/30
Filed: 2001-06-24
Abstract: When searching for new people, the current instant messaging networks typically allow users to search mainly by name or by e-mail and some of them also by interests, although one of them (Odigo) allows to search also by sex, age, area, languages, occupation and interests. However, to the best of the inventor's knowledge there is no way to systematically search in these networks for compatible dates by attributes such as education, general background, appearance, attitudes, and personality, or by reciprocal compatibility in any of the above mentioned attributes. This is a waste of a huge potential since some of these networks already have more than dozens of millions of people. Also, Odigo allows searching by only among people currently connected, which means that highly compatible dates can be missed just because they don't happen to be connected at exactly the time of the search. The present invention is a novel concept which applies computer dating to the context of instant messaging, in a systematic and flexible way that to the best of the inventor's knowledge has never been done before. This system and method enable the user to search and find instantly compatible dates in instant messaging networks on the basis of attribute search or 1-way compatibility search or 2-way compatibility search instead of being limited to search only by the limited options described above, and to search either for potential dates that are currently Online or Offline, and also take advantage of many additional features, and especially features that are based on improved integration between computer dating and instant messaging.
